qdosmsq:pe:vectors:opw

This vector emulates three QDOS vectors allowing their use with WMAN colours.

Vector	Value in D0.L	Action
UT_WINDW/OPW_WIND	$C4	Sets a window
UT_CON/OPW_CON	$C6	Sets a console window
UT_SCR/OPW_SCR	$C8	Sets a screen window

Call Parameters		Return Parameters
D0.L	See above	D0.L	Error return.
		D1.L	Corrupted.
		D2.L	Corrupted.
		D3.L	Corrupted.
A0.L	Pointer to name	A0.L	Channel ID
A1.L	Pointer to block	A1.L	Corrupted.
		A2.L	Corrupted.
		A3.L	Corrupted.

As for the QDOS vectors

The block to which A1.L points contains colours. This applies to all three vectors. For UT_WINDW/OPW_WIND the block contains in addition the window size and origin.

Address	Item
$00	Border colour (word)
$02	Border width (word)
$04	Paper/strip colour (word)
$06	Ink colour (word)

In addition for UT_WINDW/OPW_WIND

Address	Item
$08	Window width (word)
$0A	Window height (word)
$0C	X-origin (word)
$0E	Y-origin (word)
